NVIDIA NVIDIA-Certified Professional AI Networking NCP-AIN Exam Dumps: Updated Questions & Answers (April 2026)

The NVIDIA NVUE Collection for Ansible includes pre-built roles designed to streamline automation tasks across various switch models and configurations. These roles encapsulate common network configurations, allowing for efficient and consistent deployment.​

By utilizing these roles, network administrators can:​

Apply standardized configurations across different devices.​

Reduce the complexity of playbooks by reusing modular components.​

Ensure consistency and compliance with organizational policies.​

This approach aligns with Ansible best practices, promoting maintainability and scalability in network automation.​

To perform Flow Analysis with NetQ, the following prerequisites must be met:​

Cumulus Linux Version : NetQ Flow Analysis requires Cumulus Linux 5.x or later.​

Switch Hardware : The feature is supported on Spectrum-2 and later switch models.​

Lifecycle Management (LCM) : LCM must be enabled to utilize Flow Analysis capabilities.​

These requirements ensure compatibility and proper functioning of the Flow Analysis feature within NetQ.​

In DPU Mode , the ARM cores on BlueField own the NIC data path , while still allowing the host system to access the DPU OS (via OOB or virtio) .

From NVIDIA BlueField Documentation:

"In DPU Mode, the data path is offloaded to the BlueField Arm cores, enabling advanced security and networking functions, while still allowing host access to the BlueField OS."

This is different from:

NIC Mode : Data path controlled by host, ARM cores inactive.

Separated Host Mode : Complete isolation; host cannot access DPU OS.

Restricted Mode : Limited host access to DPU OS, but without full offload capabilities.

MLNX-OS, the operating system for NVIDIA's networking devices, defines two primary user account types: admin and monitor . The admin account has full administrative privileges, allowing for complete configuration and management of the system. The monitor account, on the other hand, is designed for users who need to view system configurations and statuses without making any changes. This separation ensures a clear distinction between users who manage the system and those who monitor its operations.​

Reference Extracts from NVIDIA Documentation:

"There are two user roles or account types: admin and monitor. As 'admin', the user is privileged to run all the available commands. As 'monitor', the user can run commands that show system configuration and status, or set terminal settings."​

MLNX-OS is the network operating system used on NVIDIA’s Mellanox Ethernet switches, including the Spectrum family (e.g., Spectrum-4 switches in the Spectrum-X platform), designed for high-performance Ethernet networking in AI and HPC data centers. MLNX-OS provides a command-line interface (CLI) for configuring and managing switch operations, with user accounts controlling access to various commands and functions. The question asks for the two general user account types in MLNX-OS, which define the primary privilege levels for user access.

According to NVIDIA’s official MLNX-OS documentation, the two general user account types in MLNX-OS are:

monitor : This account type has read-only access, allowing users to view configurations, status, and logs but not modify settings. It is used for monitoring and troubleshooting without risking unintended changes.

admin : This account type has full read-write access, enabling users to view and modify all configurations, execute commands, and manage the switch’s operations. It is intended for administrators with complete control over the system.

These two account types represent the primary privilege levels in MLNX-OS, providing a clear distinction between read-only monitoring and full administrative access.

Exact Extract from NVIDIA Documentation:

“MLNX-OS supports two primary user account types for managing switch operations:

monitor : Users with monitor privileges have read-only access to the system. They can view configuration details, system status, and logs but cannot make changes to the configuration.

admin : Users with admin privileges have full read-write access, allowing them to configure, manage, and troubleshoot all aspects of the switch, including executing privileged commands. These account types ensure secure and controlled access to the switch’s management functions.” — NVIDIA MLNX-OS User Manual

This extract confirms that options B (monitor) and C (admin) are the correct answers. These account types are the standard privilege levels in MLNX-OS, used to manage access for monitoring and administrative tasks on Spectrum switches, including those in Spectrum-X deployments.

NVIDIA NetQ is a network operations tool that provides real-time visibility and automated validation of the network fabric. It helps in identifying misconfigurations, monitoring network health, and ensuring that the fabric meets the required specifications for AI workloads.​

The NVIDIA UFM Cyber-AI Platform is specifically designed to enhance security and operational efficiency in InfiniBand data centers. It leverages AI-powered analytics to detect security threats, operational anomalies, and predict potential network failures. By analyzing real-time telemetry data, it identifies abnormal behaviors and performance degradation, enabling proactive maintenance and threat mitigation.​

This platform integrates with existing UFM Enterprise and Telemetry services to provide a comprehensive view of the network's health and security posture. It utilizes machine learning algorithms to establish baselines for normal operations and detect deviations that may indicate security breaches or hardware issues.​

EVPN Multi-homing enables active-active redundancy without inter-switch links by using overlay routing over VXLAN and distributed control plane using BGP EVPN.

From the official NVIDIA Cumulus Linux EVPN Multihoming Documentation :

"EVPN multihoming allows multiple Top-of-Rack (ToR) switches to connect to the same server while maintaining full layer-2 redundancy without the need for inter-switch links or traditional MLAG configuration."

Key benefits:

Simplified topology (no ISL/peer-link needed)

BGP-based control plane

Fast convergence

Active-active links per host NIC

Incorrect Options:

MLAG requires ISL between switches and peer-link configuration.

VSS (Virtual Switching System) is a Cisco term, not supported in NVIDIA networking.

The Network Traffic Map in NVIDIA's Unified Fabric Manager (UFM) provides a visual representation of the network topology and traffic flows, which is particularly useful for identifying congestion points, verifying network configurations, and optimizing workload distribution.

However, when troubleshooting a single node's hardware failure, the Network Traffic Map is less effective, as it focuses on network-level issues rather than individual hardware components.​

To upgrade the MLNX-OS on InfiniBand switches, the recommended procedure is as follows:​

Connect to the switch via SSH : Establish a secure shell connection to the switch using its management IP address.​

Fetch the MLNX-OS software image : Obtain the appropriate MLNX-OS software image from the official source or repository.​

Use the 'install' command to perform the upgrade : Execute the 'install' command on the switch to initiate the upgrade process with the fetched software image.​

This method ensures a smooth and efficient upgrade without the need for physical intervention or service disruption.​

Reference Extracts from NVIDIA Documentation:

"Click on Systems → MLNX-OS Upgrade. Select the desired upgrade method (e.g. 'Install from local file'). Select your image and click 'Install Image'."

NVIDIA NetQ is a highly scalable network operations toolset that provides visibility, troubleshooting, and validation of networks in real-time. It delivers actionable insights and operational intelligence about the health of data center networks—from the container or host all the way to the switch and port—enabling a NetDevOps approach.

NetQ can be used as the functional test platform for the network CI/CD in conjunction with NVIDIA Air. Customers benefit from testing the new configuration with NetQ in the NVIDIA Air environment (“digital twin”) and fix errors before deploying to their production. ​
